The faster i go, the greater the lag...with the end result: me crashing into a wall after a half second delay. Other than that, Fun and challenging game, Good work. :)
It also might be interesting to add a highscore table for keyboard users only, this could add a new dimension to the challenge this game already is. (If there is a way to seperate these 2)
